IMPROVED 'nnrniennaron To ALL WHoM IT MAY ooNonnnz Beit knownV that I,JAMB H. HOLL INGSWORTII, of the city of Philadelphia, in the county ofPhiladelphia, inthe State of Pennsylvania, have invented a new anduseful Improvcment in Refrigerators;" and 'I do hereby -Ideal-are thatthe following is a `full and exect description of myinvention',`reference 'being had to thoncc`z 1npnnying dra-wings, makinga part of this specification, in whieh-- Figurc 1 is an elevation viewof my refrigerator. r i

.Figure 2 is av sectional elevation of the same.

The object of my invention is to provide a refrigerator'of. cheapconstruction, 'and socontrivcd that it is kept vcl'y cold in alllitsparts without the use of ice or 'a'uy chemical oolin'g orfre'eziug-compound.

To enable others skilled in the art to make and use my invention, I willnow proeeed to dcscribe its construcztion'end operation. l I i i `A is'the casing or outside Wood (or other suitable material) work of myrefrigerator. It may be made cubic, ;or round, or ornamental, infactfany Shape t'o suit the taste'of the manufacturer and buyer. i

B isfa box, ofitin orany other suitable metal, mad'e so as to fitinsidegthe outside one, A; B'being smaller by, say, onc-fo'nrth orone-half an'inch than box A, the space'between the two being filled byplaster, P. i

The sides of tinlboxBgo up as high as those ofbox A, but the top T ofBissetsome tu'oor three inehes lower, so as to a'llow a recossor space, SP, between top T of box Band cover C of box,A.

The side of 'box B oppositetojhe doors 'is so set in as to allow,between the back of box A'and LB, a space of about one -or one and ahalf inch, for the purpose as hereinafter sho'irn, i

Now, on the top ;halfspace S P between top of B and top of A: i

The.-balanee of said space 'isfilled up with common salt, and the coilhaving been made soas to allow a little space between' each eoil ofpipe, the s alt is made tolfill up those spces, sothatthe pipes are, ullalong their ;parcours, ontirely surrounded by salt.

The enter end of' the coil is brought down in the spa-ce between the-baeks of box B and box as shou'n 'by dotte dJines C' P' in fig. 2, andcomes out inO,lwhere a, spout, S D, is'set,

The starting end E of the coil is made' to stand up so as to be inconnection with'the mi of a. Walter-tank or reservoir, R, which isplaced on top of cover C of box A;

f'he said reserroir is made of tin or. any suitable metal, and composedof two lmetal back of boai lic boxes, otflanj' shape to Fruit, inserted,the smaller into the larger, ivith intermediate space filled, as in'therefrigerator itself, ,i'ith plnjsterf Water, W, being pourcd into R,goes off let out by stoppingpr opening O D. i ,i Before reaclli'ng spoutS-D, theu'ater has to travel through coil C P, which-keeps it a longwhile in the ipesA surrounded :with salt, which, being a bad' conductorof heat,` eools the water, which `reaches spout S D always fresh vendcold. i i l' i VThe outside of my refrigerator is pro.vi

ded with doors D, in number to suit, and the inside Partition-ed so It;is obviouc that the temperature inside is very cold, partly by thenoncon luctor qualities of the salt on thtop, and also the 'snvelope ofplaster. all round the box B.

.A small space, X,.is provided on both sidcs of the coil of pipes, andlioles moll be bored through lthe sides of box A, so as to correspondwith X, and allow a'frce current of air to ciroulate around the coil, ifdcsircih The pipes I use may be either inetellic or g'utta perclm, Indiarubber, or any suitable material. I. Having thus deseribed i'nvcntion,what I elnim, and desire to vsecure by Letters Iftent of the UnitedStates, is-- Ooil of pipes C P and pipes G P', water-tankvV, outer andinside boxes and B,'salt S'S,`t`he whole combined and construeted andOperating for the purpoc and the mannerhenein desci'ibed and set for-th,
